Take your iPhone XS on a jog with running caseIf you plan on taking your iPhone XS with you on a jog, then you'll want either a heavy duty case or an armband, like the Running Buddy XL. A heavy-duty case, like the Supcase Unicorn Beetle Style will protect it from bumps in your pocket and drops if the worst should happen. An armband gets it out of your pocket altogether and up on your bicep for quick access. Whichever you prefer, these options should suit you well.
No belt required
